mindspore.ops.sgn
- mindspore.ops.sgn(input)[source]
Extension of
mindspore.ops.sign()
in complex domain. For real number input, this function is the same asmindspore.ops.sign()
. For complex input, this function is calculated according to the following formula.\[\begin{split}\text{out}_{i} = \begin{cases} 0 & |\text{input}_i| == 0 \\ \frac{{\text{input}_i}}{|{\text{input}_i}|} & \text{otherwise} \end{cases}\end{split}\]- Parameters
input (Tensor) – The input value.
- Returns
Tensor, the sgn of input.
- Raises
TypeError – If input is not a Tensor.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> import mindspore as ms >>> from mindspore import ops >>> input = ms.Tensor([[3 + 4j, 7 - 24j, 0, 6 + 8j, 8], [15 + 20j, 7 - 24j, 0, 3 + 4j, 20]], dtype=ms.complex64) >>> output = ops.sgn(input) >>> print(output) [[0.6 +0.8j 0.28-0.96j 0. +0.j 0.6 +0.8j 1. +0.j ] [0.6 +0.8j 0.28-0.96j 0. +0.j 0.6 +0.8j 1. +0.j ]]
